title: [Cryosurgery and laser surgery as a therapy of malignant and benign laryngeal processes (author's transl)].
abstract: Cryosurgery of the larynx is still in a state of development. In the treatment of laryngeal papillomas cryosurgery has been quite successful. The use of cryosurgery in laryngo-hypopharyngeal carcinoma and in laryngeal stenosis is so far restricted to special indications (old age, risk patients). A combination of cryosurgery with telecobalt irradiation has proved valuable in the managemenmt of tumors. After the basic physics of laser radiation are explained, the principle mechanisms of interaction between the CO2-laser and human tissue are mentioned. This is followed by the description of the different indications for laser surgery in the larynx. A chordectomy and the opening of a subglottic stenosis with the laser beam are described and documented with photographs. Finally there is an outlook to an eventually broader spectrum of indications for laser surgery in the ENT-field.
